byteview
An immutable byte slice that may be inlined, and can be partially cloned without heap allocation.
Think of it as a specialized Arc<[u8]> that can be inlined (skip allocation for small values) and no weak count.
byteview was designed to speed up deserialization in lsm-tree, allow inlining of small values and reduce memory usage compared to Arc'd slices.
Values with a known length can be constructed 2-2.5x faster than using Arc<[u8]>:
